Stens 380-944 Silver Streak Razor Trimmer Line.105 5 lb. Spool, ea, 1

What It Is

The Stens 380-944 Silver Streak Razor Trimmer Line is a 5 lb. spool of 0.105-inch diameter trimmer line designed for commercial-grade string trimmers and brush cutters. It’s built for heavy-duty cutting of thick grass, weeds, and light brush, not for light residential trimming.

Fitment & Compatibility

• Line diameter: 0.105-inch (2.7mm). Fits trimmer heads that accept this line size—check your trimmer’s manual or head markings for max/min diameter.
• Spool size: 5 lb. spool. Ensure your trimmer head can hold a spool this large; some consumer heads may require rewinding onto a smaller spool.
• Brand fit: Universal aftermarket part, not OEM for any single brand. Works with most gas trimmers (Stihl, Echo, Husqvarna, etc.) and compatible heads (e.g., SpeedFeed, Tap-N-Go). Verify head compatibility before buying.
• Check before buying: Measure your current line diameter. Confirm your trimmer head’s line capacity (length per load). The 5 lb. spool is heavy—ensure your trimmer’s head can handle the weight without wobbling.

Key Things to Know

• Quality: Silver Streak is a premium line with a razor-sharp edge for cleaner cuts and less engine strain. It’s more durable than standard round line but can be brittle in extreme cold.
• Installation: Moderate difficulty—rewinding a 5 lb. spool into a trimmer head takes patience. Use a line winder tool to avoid tangles. Not pre-cut; you cut to length.
• Common gotchas: The 0.105-inch line is thick—won’t fit heads designed for 0.080 or 0.095. Also, the spool is large (approx. 8” diameter) and may not fit under some trimmer guard designs. Check clearance.
• Price point: At $78, it’s a commercial buy. For home use, a smaller spool or brand-specific line costs less.

Should You Buy It

Buy this if you’re a pro or heavy-user running a commercial trimmer daily and want long-lasting, sharp-cutting line for thick vegetation. Skip it for occasional home use—a smaller, cheaper spool (e.g., 0.095” or 0.080”) will save money and hassle.
